[tex]a) \: {3}^{2} - 3 = 6[/tex]

[tex]b) {(4x + 1)}^{2} = {(4x)}^{2} + 2 \times 4x \times 1 + {1}^{2} = {16x}^{2} + 8x + 1[/tex]

[tex]5 x + 1 = 1 \\ 5x = 0 \\ x = 0[/tex]

[tex]5 \times \frac{10}{100} = 0.5 \\ 5 - 0.5 = 4.5[/tex]

Bonsoir

a) h(3) = 3² -3 = 9-3 = 6

b) (4x+1)² = 16x² + 8x + 1

c) 5x + 1 = 1

5x = 0

x = 0

d) 5 × 10 /100 = 0.5

5-0.50 = 4.50

bonne soirée
